130 / FIELDS OF INSTRUCTION ideal for plant disease development is unexcelled and offers the student opportunities to study diseases of unique crops as well as diseases of crops of national and international importance. Intimate knowledge can be gained of diseases of field, forage, forest, fruit, ornamental, pasture, range, turf, and vegetable crops in temperate, subtropical, and tropical environments. Students who anticipate study in plant pathology at the University of Florida should include .in their undergraduate programs training in botany (anato- my, cytology, physiology, systematics), chemistry (through biochemistry), introductory microbiology, physics, zoology, and mathematics. After completing PLP 6272, all students will be giv- en an oral examination covering the general and spe- cialized areas of plant pathology. Course require- ments will be determined for each individual based on his or her performance on the examination as well as his or her background and objectives. The Departments of Botany and Entomology and Nematology offer courses in, respectively, mycology and nematology. PLP 5053-Tropical Plant Pathology (3) Prereq: PLP 3002 or consent of instructor.

The Department of Political Science offers the Mas- ter of Arts degree with both a thesis and a nonthesis option and the Doctor of Philosophy degree in politi- cal science or political science international rela- tions. The Master of Arts in Teaching degree is also of- fered with a major in political science or political sci- ence international relations. The areas of specialization offered by the Depart- ment for the Ph.D., M.A., and M.A.T. include Ameri- can government and politics, comparative politics, in- ternational relations, public administration, public law, political theory, interdisciplinary urban prob- lems, and political behavior. In addition, the Department's offerings include work taken in cooper- ation with the Center for African Studies and with the Center for Latin American Studies. Programs com- posed from these areas can be used to prepare students for careers in teaching, research, and govern- ment service. The Department also offers a special- ized M.A. program in political science with an em- phasis in public administration.
